Manhole Inspections

If you have a manhole cover on your property, you will want to catch problems before they become major issues with frequent manhole inspections.

Kall Services (Midlands) Ltd can inspect your manhole visually or with our range of CCTV equipment. We can then assess any issues arising from the inspection.

Cover & Frame Replacements

Is your manhole cover noisy, broken or missing? Our engineers can provide prompt attendance to carry out manhole cover and frame replacements at your property.

A missing or damaged manhole cover is a serious issue since injury can be suffered from falling into a manhole chamber. We will assemble safety barriers, conduct a thorough examination of the surrounding frame and groundwork to ensure your new manhole cover sits securely and lasts.

Internal Manhole Repairs

Internal manhole repairs include anything from manhole benching, rechannelling to repointing.

Manhole benching refers to the sand and cement haunching that sits between the manhole walls and the channel pipes. The purpose of this is to stop rodents from leaving the system and avoid the build-up of waste in the manhole that results in blockages. To repair, or stop blockages from happening, the defective benching should be broken out and started again to ensure the manhole base is completely sealed.

Often channels break and crack, leaving snagging points for paper to catch, causing blockages within the pipe. Rechannelling the manhole pipes provides a swift solution, preventing any further blockages.

Repointing brickwork is the repair of existing pointing (the visible shaped joint between the bricks), requiring removal of the damaged material and refilling with a new mortar mix.

Manhole Constructs

New manholes can be constructed to improve access to your existing drainage system. Construction of a new manhole only takes place where all repair alternatives have been ruled out. The most common reason for manhole replacement is when wet concrete enters the manhole, hardens along the sides or underwater, and causes blockages that cannot be easily removed.

In certain cases, a new manhole is built where one did not exist previously in an effort to aid in sewer line maintenance. We can advise on where these should be constructed and to what depth in order to ensure full compliance with relevant regulations.
